Chesapeake Energy Corp. (NYSE: CHK) is delivering on its divestment plans, saying Dec. 5 it agreed to sell a package of producing Haynesville Shale acreage in northern Louisiana for about $450 million.

The deal covers 78,000 net acres, with slightly more than half—40,000 net acres—considered core to Oklahoma City-based Chesapeake. Assets include 250 wells producing 30 million cubic feet of gas per day (MMcf/d).

The buyer was not disclosed, but Reuters reported that a subsidiary of Houston-based Indigo Minerals LLC is the acquirer, citing unnamed sources.

Kirkland & Ellis LLP, which is representing the buyer in the Chesapeake deal, did not respond a request for comment about Indigo Minerals. In April 2016, the law firm advised Indigo on a $375 million acquisition in the Haynesville.
